Cavity Wall Insulation

About a third of all the heat lost in an uninsulated home escapes through the walls. By properly insulating cavity walls, you will save energy and cut costs off your heating bill.

In general, houses built from the 1990's onwards have wall insulation to keep the heat in, but if your house is older than that, it may not have any wall insulation at all.

Houses in the UK mostly have either solid walls or cavity walls:

  •            If your house was built after the 1920's, it is likely to have cavity walls. A cavity wall is made up of two walls with a gap               in between, known as the cavity; the outer leaf is usually made of brick, and the inner layer of brick or concrete block.

  •            Kinetik Energy are able to provide a comprehensive technical survey of your home to establish if the property is                       suitable for the installation cavity wall insulation. 

  •            If your property is suitable and you decide to insulate the walls we are able to engage a suitable contractor on your                   behalf to carry out the works. We only use contractors who have demonstrated to us both their technical competence               and the highest levels of customer care and quality assurance. The industry recognised guarantee will also be                           provided to for all cavity wall installations.



Cavity wall insulation explained

Many cavity walls can be insulated by injecting insulation material into the cavity from the outside. A specialist company will drill holes in the outside walls, inject insulation through the holes and then seal them with cement. The insulation materials is usually either mineral wool or polystyrene beads.

To insulate your cavity walls, the installer drills small holes around 22mm in size at intervals of around 1m in the outside wall of your home. The installer then blows insulation into the cavity using special equipment. Once all the insulation is in, the installer fills the holes in the brickwork so you'll barely notice them.

Filling cavity walls is not a job you can do yourself, you will need to employ a registered installer. A professional can do the job in around two hours for an average house with easily accessible walls. It shouldn’t make any mess.


Costs and savings

Typical installation costs of cavity wall insulation vary depending on the size of your home. But whether you live in a large detached house or small flat, you should be able to make back the installation cost in 5 years or less due to the yearly energy bill savings you will make.

Loft Insulation

A quarter of heat is lost through the roof in an uninsulated home. Insulating your loft, attic or flat roof is a simple and effective way to reduce heat loss and reduce your heating bills.

Loft insulation is effective for at least 40 years and it should pay for itself many times over. Our surveyor will advise on what level of loft insulation is needed at your home

External Wall Insulation

Insulating your solid walls could cut your heating costs considerably, and make your home more comfortable.

If your home was built before the 1920's, its external walls are probably solid walls rather than cavity walls.

  •           Solid walls have no gap, so they can’t be filled with cavity wall insulation


External wall insulation involves fixing a layer of insulation material to the wall, then covering it with a special type of render (plaster work) or cladding. The finish can be smooth, textured, painted, tiled, panelled, pebble-dashed, or finished with brick slips.

  •           It can be applied without disruption to the household.

  •           It will renew the appearance of outer walls.

  •           It will improve weatherproofing and sound resistance.

  •           It fills cracks and gaps in the brickwork, which will reduce draughts.

  •           Increases the lifespan of your walls by protecting the brickwork.

  •           Reduces condensation on internal walls and can help prevent damp (but will not solve rising or penetration damp).

  •           It is best installed at the same time as external refurbishment work to reduce the cost.

  •           It may need planning permission - check with your local council.

  •           It requires good access to the outer walls.

  •           It is not recommended if the outer walls are structurally unsound and cannot be repaired

EPC Survey

A core part of our business is the provision of Energy Performance Certificates (EPC’s) for Local Authorities,Housing Associations, landlords and homeowners looking to sell or rent their home.

Our assessors are fully trained and qualified and all have current DBS certification.


Our assessors are also able to provide Home Energy Assessments


We are able to provide these services throughout the UK

Replacement Boilers

Heating accounts for about 55 per cent of what you spend in a year on energy bills, so an efficient boiler makes a big difference.

All well-maintained boilers burn their fuel very efficiently, but they inevitably lose some heat in the hot gases that escape up the flue (a pipe for extracting fumes and supplying fresh air to the boiler). 

Modern boilers are more efficient for several reasons, but their main advantage is that they are all condensing boilers. A condensing boiler has a larger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient.

If you are thinking of replacing your boiler we are able to arrange for a survey and advice.

Legionella Investigations

What is Legionnaires’ disease?
Legionnaires’ disease is a serious and potentially fatal lung infection caused by legionella bacteria. It is usually caught by breathing in small droplets of contaminated water. Anyone can develop Legionnaires’ disease, but people are more at risk if they are more than 50 years old, are smokers, have cancer, diabetes, and chronic respiratory or kidney disease.
How does Legionella spread?
Legionella bacteria are common in natural sources of water, such as ponds, rivers and lakes. Sometimes they find their way into man-made water systems, such as domestic water supplies, cooling towers and spa pools.
Legionella bacteria can grow and reproduce when:
· water temperatures remain between 20-45°C (68-113°F) · there is sediment in the water that the bacteria can use for food – such as rust, algae and limescale · the water is stagnant.
To cause infection, legionella bacteria would normally need to be inhaled within tiny water droplets (aerosols) which can go deep into the lungs; therefore, infection would only occur after being exposed to a contaminated water source that also produces aerosols such as showers, taps or a spa pool.

Cavity Wall Insulation Extractions

Cavity wall insulation may need to be removed for various reason including the following


To resolve internal damp issue

Degrading of existing insulation material

To remedy any damage caused during the course of property maintenance


Cavity wall insulation needs to be removed only by specialist contractors using the appropriate extraction equipment.


Kinetik Energy are able to provide comprehensive extraction surveys
